The mom-of-four (Melanie, 25, Jillian, 23, Devin, 20, and Sasha, 13) is marking the holiday from her spot on stage in Broadway's The Trip to Bountiful. "I have a 3 o'clock matinee. No rest for the weary," Williams, 50, tells PEOPLE, adding, "Maybe my kids will surprise me with a dinner afterward."

Beyond the theater, she's also taking time to honor her late grandmothers, who both died after struggling with heart disease. (Her maternal grandmother died at 64 after having a massive heart attack, and her paternal grandmother died at 28.)

Star power shined on Broadway this season – and some of the big names even managed to gain Tony nominations, it was announced Tuesday morning.

Among them: Tom Hanks, in the Tony-nominated best-play contender by the late Nora Ephron, Lucky Guy; Laurie Metcalf, in Sharr White's The Other Place; Cicely Tyson, in a revival of Horton Foote's The Trip to Bountiful; Holland Taylor, in the play about the late, outspoken Texas governor Ann Richards, written by Taylor herself, Ann; David Hyde Pierce, in Christopher Durang's best-play nominee Vanya and Sonia and Masha and Spike; Nathan Lane, in Douglas Carter Beane's The Nance.

In the best musical category, the nominees are Bring It On, A Christmas Story, Matilda and Kinky Boots, which received the most nominations of any show: 13, including a nod for its Cyndi Lauper-written score.

Best play contenders, besides Lucky Guy and the side-splitting homage to Chekhov, Vanya, are Richard Greenberg's The Assembled Parties and Colm Tólbin's The Testament of Mary.
